United States Patent 3,172,656 SHEET JOGGING MECHANISM FOR BELTTRANSPORTFNG IVIEANS Luis Mestre, 305 E. 46th St., New York, N.Y. FiledJan. 18, 1963, Ser. No. 252,529 31 Claims. (Cl. 271-48) The inventionrelates to a jogging mechanism for jogging a plurality or book of sheetsto bring them into precise lateral alinement and to bring the ends ofthe book of sheets into more accurate end to end alinement. This joggingmechanism is used on the Mestre Collating Machine S.N. 191,141, filedApril 30, 1962, now Patent No. 3,108,797, dated October 29, 1963. Thiscollator provides a plurality of storage pockets, each containing a pileof one sheet, and ejects one sheet from each storage pocket and deliversthis book of sheets in overlapping but spaced end to end relation to atransporting means having sheet stop means. The sheets of the book arebrought into approximate end to end alinement at the stop. It is nowdesired to staple the book of sheets in at least one corner While thesheets are halted at the stop means before passing the book to a depositplatform. When the sheets are stapled on the transporting means at thestop, it is desirable that the sheet be brought into more preciselateral alinement and more precise end to end alinement. The joggingmechanism to be described herein efiects this more precise alinement.

It is an object of the invention to construct a jogging mechanismincluding a lateral jogging means and a longitudinal jogging means for abook of sheets which have been halted at a stop in the transportingmeans following collating of the sheets.

Another object of the invention is to provide jogging mechanism as abovein which the lateral jogging means are adjustable laterally so thatsheets of different widths may be accommodated.

Another object is to provide jogging mechanism in which the end orlongitudinal jogging means is adjustable longitudinally so that sheetsof different lengths may be accommodated.

Another object is to construct a combination of a roller longitudinalalining means and a longitudinal jogging means.

A further object is to construct an improved roller alining means forlongitudinal alinement.

A still further object is to construct a jogging means for a book ofsheets in which adjustability is made without change of the operatingmeans which jogs the jogging means.

Another object is to provide a combination of the above means for bothlateral and longitudinal jogging of a book of sheets.

Other objects of the invention will be more apparent from the followingdescription when taken in connection with the accompanying drawingsillustrating a preferred embodiment in which:

FIG. 7 is a side view of the roller alining means;

FIG. 8 is a view showing the drive connection between sheetstransporting belts.

In the collator above identified a plurality of storage pockets areprovided, each of which has a different sheet or page of a book. Some ofthe numerals used herein are those used in the prior application for thesame structure. Means are provided to eject one sheet from each pocketat the same or approximately the same time and feed the same inoverlying relation but with their ends progressively spaced apart adistance less than sheet length such as two or three inches. Theseejected sheets forming one book are fed in spaced overlapping relationto the sheet transporting means 22. A frame 21, 21a of necessary. formis provided, which carries pairs of feed belts 141 and 158, two pairsbeing shown. In the collator of the prior application the transportingmeans are preferably inclined. Each belt 141 passes over rollers 145(FIG. 8) at the top of the frame 21 and over roller 147 at the bottom ofthe frame from which each belt passes to the collating operation andthen back to roller 145. The belt is driven directly by roller 145. Theset of feed belts 158 pass over a roller 159 around roller 142 at thetop of the frame, over roller 145 and pass around roller 161 at thebottom. The inner span of the belts 153 are driven downwardly, as viewedin FIG. 1, by contact of each belt 158 with its cooperating belt 141 andparticularly by the arcuate contact, provided between the belts aroundthe driving roller 145. The path of the sheets is longitudinally betweenthe belts 141 and the contacting portion or inner span of the belt 158.The roller 145 and hence the belts of the transporting means arecontinuously driven by means including a belt and pulley 153. Asupporting plate 166 carried by the frame gives additional support tothe sheets when being transported by the belts.

A stop operating means 165a controls a stop means 165 which is movedinto and away from the path of movement of these sheets, which stopmeans is engaged by the lowermost or forward edge thereof and halts thesheets thereagainst. It is while the book of sheets are halted by thestop means that jogging for alinement and stapling takes place. Any formof stop means may be provided. Preferably the stop operating means 165adepresses the stop means from the path of the book of sheets so that thebook may be advanced thereover by the transporting belts to a depositplatform at the end of the transporting means after having been joggedinto alinement and stapled. This stop operating means is described indetail in the above identified prior application and so far as thejogging mechanism therein is concerned it need only be mentioned thatthe stop means is raised or brought into the path of the sheets untilthe book of sheets are jogged into alinement and stapled, after whichthe stop means is depressed or retracted out of the path of the sheetsand the belts of the transporting means carries the book to a depositplatform. In the event that there is one or more sheets missing or oneor more extra sheets included in the book, as determined by gaging meanslocated at the stop position, the book is carried to a rejection bin.

The alining mechanism includes longitudinal jogging means and lateraljogging means. The longitudinal jogging means is mounted on a carriage25, FIG. 6, desirably adjustably mounted on the frame 21 andparticularly on side plates 21a forming a part of the frame. Clamps 27lock the carriage in adjusted position. This carriage also carries aroller longitudinal alining means to be described hereinafter so that ittoo is adjusted longitudinally with the adjustment of the longitudinaljogging means.

The longitudinal jogging means includes a jogging finger 30, FIG. 3,which is mounted for vertical movement between the sides 31 of a bracket32, carried by the carriage 25. This jogging finger carries a pin 33which is in a slot 34 carried by a bell crank lever 35 which lever ispivotally mounted on a pivot 36 carried by a bracket 32. The arm 37 ofthis bell crank lever carries a roller 38 mounted upon a pin 39. Theroller engages the edge of a finger operating bar 40 having a pair ofspaced inclined slots 41 therein in which is received a pin 42 carriedby the frame 21 or particularly by cross bars forming part of the frame,and a bracket 49. Upon vertical movement of the operating bar, it alsomoves laterally by virtue of the inclined slots and pivots the bellcrank lever to move the jogger 30 longitudinally into engagement withthe upper or rear edges of the sheets of the book and jog them intoalincment against the stop means 165a. The inclined slots 41 may becarried by one of the parts including the finger operating bar 40 aboutthe frame and the pins 42 carried by the other part.

Means are provided to move the operating bar longitudinally, as aconsequence of which the operating bar moves laterally in a parallelmotion through the camming action of the inclined slots 41 and the pins42 received in the slots. This longitudinal movement of the operatingbar 40 is secured by means of a link 45 secured to the bar at one endthereof by a pin 44 and the other end of the link is secured by pin 46to a lever 47 carried by a pivot rod 48 and rotatably mounted in theframe 21a and a bracket 49 secured to the frame in any suitable manner.The shaft 48 carries a lever 50, which is oscillated in time sequencewith respect to the other operations of the collator and particularlythe stop means. The lever 56 carries a roller 51 on the end thereof.

An operating connection is provided between the lever and the drive orcam shaft 26 mounted in the collator frame 20 and driven by a collatormotor, in order to oscillate the jogger in timed sequence with the otheroperations of the collator and particularly with the projection of thestop means 165 into and away from the path of movement of the sheets. Inother words the longitudinal jogger is oscillated after the stop means165 has been moved into stop position and before it is retracted fromstop position. It is during the same period but after jogging that thebook of sheets is stapled. The lever 50 is operated by a flange 54carried by a link 55, one end of which is connected by a pivot pin 56 toa lever 57 pivotally mounted on a pivot 58 carried by the frame 21.

Connecting means is provided to pivot the lever 57 and this means isconstructed so that the frame 21 may be swung away from the collator.The operating connection is secured by having a roller 59 carried by thelever 57 which is engaged by a lever 60 pivotally mounted on thecollator frame 20 on pivot 61. The lever is connected through a pin 62to a link 63, the lower end of which link carries a cam roller 64 whichengages a cam 65 secured to the drive or cam shaft 26. The cam 65 isshown with a single raised portion so that one oscillation of thejogging mechanism occurs for each revolution of the shaft. The lower endof the link 63 is guided by a swing link 66 pivoted to the link by a pin67 and the other end of the link is pivotally mounted on a pivot 68carried by the frame.

Means are provided, FIG. 4, to move the longitudinal jogging means orfinger into the path of movement of the sheets and after jogging is thenretracted or depressed away therefrom so that the next book of sheetspasses thereover. One of the parts including the fingers 30 and thebracket 31 includes an inclined slot means for moving the jogging fingeraway from or below the path of movement of the sheets and slot engagingmeans is carried by the other part engaging in the inclined slot means.In the construction illustrated the inclined slot means includes a slot72 carried by each side 31 of the bracket means 32. The jogging finger30 has spaced angularly extending flanges 73 received between the sides31. The flanges carry a pin 74 each end of which engages its respectiveslot to form slot engaging means. This structure shifts the joggingfinger 30 downwardly below the path of movement of the sheets in onedirection of longitudinal movement of the finger and upwardly uponmovement in the other direction. Preferably each inclined slot has astraight or parallel portion 75 at the end thereof so that when thejogging finger 30 has been brought fully into the path of movement ofthe sheets, the finger moves horizontally or parallel with the sheets inperforming the. jogging of the sheets. The longitudinal jogging fingerand" its connections are returned to initial position by a spring 76connected between the finger lever and the bracket 32.

The lateral sheet jogging means, FIGS. 1 and 5, includes a pair ofspaced jogging rails 79 extending longitudinally with respect to thetransporting means. Each rail is secured to its slide bar 80, FIG. 5, bya flange 87. Each rail is oscillated outwardly and a spring 81 connectedwith the two slide bars pulls the bars and rails inwardly towards eachother. Each slide bar carries an adjusting slot 82 in order toadjustably secure each jogging rail to its slidebar by means of suitableclamping means 83 engaging the flange 87, and slide bar. These joggingrails therefore may be spaced apart depending upon the width of thesheets to be jogged or alined. The slide bars are mounted for lateralmovement on the frame 21 or particularly. on a cross bar 84 whichcarries guide pins 85 which are received in slots 86 carried by eachslide bar 80. The cross bar 84is secured to the side plates 21a andhence forms a part of the frame.

Operating means is provided to oscillate each slide bar and its' raillaterally. The means particularly illustrated is a cam 89 pivotallymounted on a pivot 90 carried by the cross bar 84 which cam is locatedbetween spaced but adjacent inner ends of the slide bars 30. Uponturning of the cam both slide bars and their jogging rails areoscillated laterally outwardly and upon return of the cam to initialposition the spring 31 pulls the slide bars and rails inwardly as wellas maintaining the adjacent ends of the slide bars against the cam.

Cam operating means is provided to oscillate the lateral jogging cam 89,which means includes a link 93 pivotally secured by a pin 94 to the cam89, which link is slidably mounted in a bushing 95 secured to a sideplate 21a. The link 93 carries a roller 96 mounted on its end on a pin97, which roller engages a bell crank lever 98. This lever is pivotallymounted on the frame on a pivot 99 carried by a bracket 102 secured tothe frame and the other arm 100 of the bell crank lever carries a 0 pin101 connecting the lever to the link 55. The oscillation of the joggingcam 89 and the jogging rails 79 is, therefore, secured from the same cam65 which oscillates the longitudinal jogging finger 30. With a singleprojection on the cam 65, the lateral jogging occurs once for eachrevolution of the shaft 26.

It is desirable that the lateral jogging means have means to restrainthe longitudinal edges of the sheets from displacement away from theother sheets. This edge restraining means includes a space bar 104 foreach jogging rail which space bar is secured to its rail Why a screw105. The space bar has its upper end angled outwardly to guide thelongitudinal edges of the sheets between the jogging rail and the spacebar. The space bar may be removed and substituted by a jogging unit withlong studs to' provide for sheets narrower than the range of adjustmentprovided.

It has been mentioned that the collator delivers a book of sheets to thetransporting means with the leading edges of the sheets in longitudinalspaced relation between the arraese feed belts 141 and the inner band orspan of the feed belts 158. Since the first and the last sheet of a bookof sheets is in direct contact with one of the feed belts, these sheetsare positively moved thereby into contact with the stop means. Usuallythe frictional engagement between the sheets carries each of theintermediate sheets against or adjacent to the stop. This does notalways occurs, however, so that a roller alining means, FIGS. 6, 7, isprovided just beyond the trailing edge of the sheets. This rolleralining means engages any sheet or sheets which may not have been fedinto contact with or adjacent to the stop and feeds them into thisposition. This assures that the trailing edges of the sheets are notprojecting rearwardly far enough to interfere with the more precisejogging of the longitudinal jogging finger 30. Preferably the rolleradvancing or alining means is driven by the feed belts 158. The rolleralining means may be that described in the above identified application.The roller alining means to be described is an improvement on that ofthe earlier application. It is carried by the carriage 25, so that it isadjustable longitudinally with the longitudinal jogging finger in orderto accommodate for sheets of greater or lesser length making up thebook.

The roller alining means includes back-up roller means comprising a pairof rollers 111 rotatably mounted on a rod 112, which rod is mounted inslots 109carried by the carriage 25 for movement towards a drive roller.Springs 113 propel the rod and rollers upwardly as viewed in FIG. 6. Theperiphery of the back-up roller 111 is in the region of the level of thesheets positioned between the transporting belts 141 and 158. Alining oradvancing roller means such as two rollers 114 are rotatably mountedsuch as on shaft 115 which is carried by a bracket 116 secured to thecarriage 25. There is an advancing roller 114 for each of the back-uprollers 111 and in alignment or contact therewith. The sheets of thebook pass between the rollers 111 and 114.

Advancing or feed rollers 114 are rotated by any suitable means andconveniently from the transporting belts. The roller 114 is suitablysecured to a driving roller 117. This may be a direct connection, asshown or by securing both to the shaft 115. The driving roller 117 issmaller in diameter than the advancing roller 114 to provide clearancefor the transporting belt 158. The driven roller 117 and hence theadvancing roller 114 must be rotated in a direction to feed sheetsdownwardly between the transporting belts against the stop means oradjacent thereto. The rollers 111 and 114 are located just above thelength of a sheet measuring from the stop means. Any sheet or sheetswhich have not been advanced by the transporting belts into contact withthe stop means and hence project rearwardly therefrom are engaged by theadvancing rollers and advanced toward the stop means. The advancingroller 114 may be rotated from the transporting belt 158 andparticularly the upper pass or band of this belt. Since this upper passis moving upwardly, the periphery of the advancing roller on theopposite side thereof is moving downwardly, as viewed in FIG. 8. Thedriving roller 117 is therefore held in engagement with the upper passor band of this belt.

Means are provided to press the upper pass of the transporting belt 158into contact with the periphery of the driving roller 117. This meansincludes a pressure roller means comprising a pair of spaced pressurerollers 121 rotatably mounted on a shaft 122, which shaft is carried bya pressure roller bracket 123. This bracket is pivotally mounted on thebracket 116 by pins 124. The pressure rollers 121 are spaced from thedriving rollers 117 and shown particularly as forwardly thereof, so thatthe upper pass of the belt 158, in passing over the driving roller 117and under the pressure roller 121 provides an arcuate contact of thebelt 158 with the driving roller. Suitable means are provided to pressthe pressure roller 121 against the belt; that particularly shownincludes a screw 125 carried by an arm 126 secured to the bracket 6 116and located so that the screw engages the bracket 123. A pin 127 iscarried by the bracket 116 adjacent to each roller 114 and the path ofthe sheets and assures that the sheets follow the transporting belts.

Any sheets which project beyond the trailing edge because they have notbeen brought into contact with the stop means or adjacent thereto areengaged by the feed rolls and advance into contact therewith or adjacentthereto. There are, therefore, no rearwardly projecting ends of thesheets in the path of the longitudinal jogging means to interferetherewith. As a consequence the longitudinal jogging means jogs thesheets so that the forward edges of the sheets are brought into contactwith the stop means so that they are accurately alined to be stapled inthis position.

In order to assist in guiding the carriage 25 for adjustt merit, a guidebar 130 is secured to each side plate 21a and engages an edge member 134carried by the carriage. Preferably too, each guide bar has rack teeth131 which are engaged by a gear 132 secured to a shaft 133 so thatadjustment of the carriage is smoother. Also the supporting plate means166 will have laterally extending grooves 135 to receive the ends of thejogging rails 79 to bring the end surface into alinement with the top ofthe supporting plate means 166.

This invention is presented to fill a need for improvements in a sheetjogging means. It is understood that various modifications in structure,as well as changes in mode of operation, assembly and manner of use, mayand often do occur to those skilled in the art, especially afterbenefiting from the teachings of the invention.
